Is vaginal discharge, or perhaps more appropriately moistness, common after having the depo-provera shot?

Can be: It has a lot of potential side effect to include : irregular bleeding , weight gain ectopic pregnancy, loss of bone mineral density, and it should not be used longer than two years. My advise to u before taking any medication to get familiar w side effect . However, it does not mean all listed side effect will happen to u, but since u will be aware of them u can be on the look out.
